“…Many researchers have observed that plant community characteristics were usually relatively lower in species richness and plant density in the earlier stages of succession following farmland abandonment (Keever 1983, Carpenter et al 1990, El-Sheikh 2005, and our study further supports that finding. For example, we found a relatively lower species richness, plant density, FRLD, and FRAD (Table 1, Fig 4 a,b).…”

“…In this study, we found that soil moisture decreased with vegetation succession time and ascribed this to the rapid development of plant communities that vigorously extracted water from the soil. A similar conclusion has been reported by Davis et al (1998) and El-Sheikh (2005). During the same period, there were no significant changes in either available P or available N contents.…”

Aboveground and belowground changes during vegetation restoration and vegetation successions need to be characterized in relation to their individual responses to changes in soil resources. We examined above-and belowground vegetation characteristics, soil moisture, and nutrient status at the end of the growing season in 2006 in plots with vegetation succession ages of 2, 4, 6, and 8 years (two replicates each) that had been established on abandoned cropland, where potatoes had been grown for 3 years, using hoe and plow cultivation, immediately prior to vegetation clearance and subsequent natural plant colonization. A plant community comprising pioneer species [e.g., Artemisia capillaries, (subshrub)] was characterized by low levels of species richness (7.5±1.4 species m −2 ), plant density (35.7± 4.2 stems m −2 ), fine root length density (940.1± 90.1 m m −2 ), and root area density (2.3±0.3 m 2 m −2 ) that increased rapidly with time. Aboveground and belowground characteristics of both A. capillaries and the later successional species, Stipa bungeana (C3 perennial grass), increased in the first 6 years, but in the following 2 years A. capillaries declined while S. bungeana thrived. Thus, the fine root length density of A. capillaries, 812.4 m m −2 after 2 years, changed by a factor of 1.7, 2.0, and 0.4 in the 4th, 6th, and 8th years, whereas that of S. bungeana changed from 278.4 m m −2 , after 4 years, and by 1.7 and 23.3 times in the 6th and 8th years, respectively. Secondary vegetation succession resulted in reduced soil moisture contents. Soil available P and N mainly influenced aboveground characteristics, while soil moisture mainly influenced belowground characteristics. However, soil moisture had no significant affect on S. bungeana belowground characteristics at the population level in this semiarid region.

“…and Tamarix nilotica. This change occurred fast and is similar to that found by Halwagy (1963) in his study on the vegetation succession in a Nile Island in Sudan, and the study of El-Sheikh (2005) on plant succession of the abandoned fields in Egypt.…”

“…In order to explain a plant succession on a new substrate some authors suggested a micro-site approach, taking into account small-scale differences in microclimate, disturbance levels, water supply, grain size and chemical quality of the substrate, and soil development (e.g. Burga, 1999;Burga et al, 2010;El-Sheikh, 2005;Tintner and Klug, 2011). The present study aims at elucidating the crucial factors governing plant establishment on the new substrate area, such as time, micro-relief and edaphic factors, using a multi-method approach including: 1 -floristic relevés along a chronosequence covering 10 years (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010); 2 -description of vegetation structure, and 3 -soil analyses.…”

“…With the exception of climatic factors, changes in soil resources are important determinants of vegetation features at small spatial scales (El-Demerdash et al 1995;Dodd and Lauenroth 1997;Havstad et al 2000;Miki and Kondoh 2002;Dale and Adams 2003;Oztas et al 2003). Most recent studies of vegetation succession in arid regions have examined vegetative dynamics after human disturbance, such as recovery after construction (pipeline corridors, power transmission lines and transportation routes), mining, farming (old fields, abandoned fields and field management), abandonment of population centers (Carpenter et al 1986;Webb et al 1988;Harmer et al 2001;Warren et al 2002;Ejrnes et al 2003;EI-Sheikh 2005), and natural events such as landslides (Singh et al 2001;Sparling et al 2003). Few studies have monitored the long-term processes of vegetation change associated with stabilization of unstable sand dune systems.…”

Changes in soil and vegetation following stabilisation of dunes in the southeastern fringe of the Tengger Desert, China

Properties of the soil and sand-binding vegetation were measured at five sites plus a control on dunes of the Tengger Desert stabilized for periods of up to 50 years. In the topsoil, fine particles, total N, P, K and organic matter increased significantly with increasing site age. However, there were no significant changes in deeper soil profiles (>0.4 m depth). Soil pH, calcium carbonate content, and total salt content tended to increase with age. Soil water in the topsoil changed little with increasing age, but was closely related to rainfall during the 50-year period. For deeper soil layers (0.4-3.0 m) soil water decreased significantly with age. After revegetation, the number of herbaceous species increased up to 30 years and then levelled off to 12-14 species, whereas the number of shrub species decreased from the 10 initial sand-binding species to only 3 species. Shrub cover decreased from a highest average of about 33% to the current 9%, whereas cover and biomass of herbaceous species increased throughout succession from 1956 to 2006. The development of soil and cryptogamic crusts on the surface of stabilized dunes enhanced the colonization and establishment of herbaceous plants due to increasing water availability, clay and silt content and soil nutrients. We propose that changes in properties of the surface soil led to increased interception of water, favoring shallow rooted grasses and forbs over perennial shrubs.
